Here are a few more facts about our good friend, soil (courtesy of DoctorDirt.com) :

  • Soil is a living system.
  • Soil contains 0.01% of the Earth’s water.
  • Soil is 49% Oxygen, 33% Silicone, 7% Aluminum, 4% Iron, and 2% Carbon.
  • Fifty percent of soil is air and water. The rest is mineral and organic material.
  • In one gram of soil, the number of bacteria ranges from 100,000 to several billion.
  • There are 5000 to 7000 different species of bacteria in one gram of soil.
  • The total living matter in an acre of soil ranges from 5000 to 20,000 pounds.
  • Each year, 15 tons of dry soil per acre pass through earthworms. Earthworms eat soil to get the organic materials in it. The rest passes through them.
  • About 42 centuries ago, the Chinese used a soil map to determine taxation amounts.
  • Soil develops from geologic materials such as rocks, glacial deposits, granite, limestone, and stream sediments.

  • The stability of the foundations of our houses and buildings are determined in part by the soil they rest on.
  • Soil is much like the earth’s peel, similar to an orange peel.
  • Erosion of soil from our lands clogs rivers and dams and decreases the usefulness of soil for growing plants.

  • Cleaning up the rest of the toxic chemicals already in the environment would cost $500 to $2500 per person.
  • The United States has at least 36,000 hazardous waste sites present in our soils.
  • Soil supplies the water and nutrients necessary for plant growth.
  • Around one acre of land is use to supply the food for each person in the world.
  • An acre of corn gives off 4,000 gallons of water a day in evaporation.
